Lentri is built as a quiet, on-device workshop for your puzzle hobby. This journal explains what touches your phone, what stays inside it, and what may travel only through systems you already trust (such as your platform store). There is no Lentri account inside the product story told here: your entries begin on your hardware.
Without a Lentri login, the app does not assign you a hosted profile, username, or synced credential vault. Anything that feels like "you" inside Lentri is assembled from the puzzles you add, the photos you attach, the timers you run, and the ratings you save.
Puzzle records, progress numbers, timer state, completion notes, and paths to images are stored locally using the same kinds of structured storage mobile apps use for offline journals. Finished and in-progress imagery is kept alongside those records so the gallery views stay fast.
When you photograph a box, a progress moment, or a finished table, Lentri requests access through the operating system prompts you already know. You can revoke access later in system settings; Lentri cannot override that choice. If you import from the library instead of the camera, only the items you explicitly pick are referenced.
On platforms that ask whether an app may track you across other companies' apps and websites, Lentri follows the system sheet. Your answer is remembered on the device the way the operating system stores it.
If you choose optional purchases, the platform store handles payment details. Lentri does not type credit card numbers into its own screens as part of this journal.
Summary numbers you see (counts, totals, averages drawn from your own saved puzzles) are computed from data already on the phone. They are not a separate cloud analytics product unless a future version clearly says otherwise in release notes.
If you open linked documents in an embedded browser view, the page you load follows the rules of whoever hosts that page. Lentri only wraps the viewing experience; it does not rewrite remote servers.
Standard device backups may copy Lentri data the same way they copy other apps. If you migrate to a new phone using a manufacturer transfer tool, your puzzle archive may move with the rest of your backup bundle. Lentri does not promise a bespoke export format in this static document; ask the contact email if you need migration guidance.
If a family tablet holds Lentri, remember that anyone with the device passcode can open the app and see the same archive. For younger builders, parental controls at the system level remain the right lever.
This narrative does not describe harvesting contact lists, scanning unrelated photo albums in the background, or silently reading unrelated files. If future features need new categories of information, they should ship with fresh in-app explanations.
Email Lentri9k2xw@outlook.com for privacy-related product questions. Keep messages descriptive but avoid attaching highly personal imagery unless support explicitly requests it.
This journal does not advertise a hidden always-on map trace inside Lentri. Puzzle journaling is about your table, your lighting, and your pace. If a future build ever introduces optional location tagging for travel puzzles, that feature should ship with its own plain-language note and an obvious switch defaulting to off.
Lentri is visually oriented. Unless a labeled feature explicitly asks for microphone access for a future idea such as voice memos beside a build, you should not expect silent audio capture. Decline prompts that feel unrelated to what you tapped.
Ordinary typing inside Lentri stays on-device. If you paste text from elsewhere, that text becomes part of your entry the same way any note field would behave. Nothing here describes shipping your clipboard to a Lentri warehouse in the sky.
When something crashes, your phone may already collect anonymized crash breadcrumbs through the platform vendor. Lentri may participate in those channels the way most apps do so engineers can see stack traces. That pipeline is separate from your puzzle titles and photos.
If Lentri ever asks to nudge you about streaks or reminders, the operating system permission sheet is the gate. You can silence or revoke alerts without uninstalling the archive. Until such a feature exists, enjoy the quiet default.
Whatever keyboard you install at the system level may process keystrokes according to that keyboard vendor's practices. Lentri does not replace your keyboard; choose one you trust when typing titles or notes.
Tiles in this journal can be read in any order. The numbering is a design rhythm, not a hierarchy of importance. If two sections ever seem to disagree, the more specific in-app label on the screen you are looking at wins for that moment.
Entries remain until you delete them inside Lentri or remove the app and its data using system storage controls. Uninstalling without wiping app data may leave artifacts until the operating system reclaims space.
Protect your passcode, install system updates, and avoid sideloading modified Lentri packages from unknown sources. Integrity keeps your archive yours.
Lentri centers on photos and numbers you generate while puzzling. Platform services handle purchases and permissions prompts. Questions go to the mailbox below.
